I've been trying for the past week to verify that
telephony on my teletype
machine (model 33) is functioning properly but the biggest hurdle I am
running into is I have nothing to easily dial into. Everyone I know off hand
either don't have a modem anymore or theirs is a Winmodem which won't work.
There's only one phone line into the residence here and those bluetooth to
cellular POTS bridges are too lossy to make do and connect to a machine
here. There is that youtube video of the model 37 apparently connecting to a
system at the Living Computer Museum in 2013 (MikoF6KZjm0) where they dialed
into a BBS I've never seen listed anywhere but the number listed no longer
seems to work and in the description it states the service is no longer
available. What other public systems are still out there that will work this
speed or possibly better yet, is there anyone out there willing to try a
teletype-to-teletype conversation?
Curious as to the setup you are attempting this with, i.e. exactly what modem are you
using?
One in the base of the 33 or some common external one?
I'm not familiar with all the possible modem variations one might find in a 33, but
AIUI the modem for the 33 at the standard 110 bps was Bell 101 standard.
There's not going to be a lot to talk to out there using the old parameters.
Even if someone had an auto-baud dial-in setup out there somewhere, I wouldn't
anticipate it being compatible.
We have a 101-standard modem (in the base of a 33) around here, but have never tried it or
tried connecting it to a phone line, I'm also not familiar with it enough to know how
originate/answer issues are dealt with (whether it can do both) for such 33 to 33
communication.
